Alan Jackson Surprises Zac Brown Crowd

Brad Schmitt

The Zac Brown Band played a show at Bridgestone Arena in Nashville last night (Dec. 29). And so it probably wasn't any great surprise that Nashville-area resident Alan Jackson came out onto the stage for their duet, “As She’s Walking Away.”

But when A.J. came out, the crowd went totally bonkers, clapping, shouting, screaming and generally showering him with love. After the song was over, Alan and Zac exchanged an awkward hug, and Zac told the crowd, essentially, that’s a country music legend right there.
